Gilmer County, GA: Radon Risk Data
EPA predicts average indoor levels between 2–4 pCi/L · Source: EPA, CDC
Tipper's take on Gilmer County
Gilmer County is in EPA Zone 2, a moderate risk classification. The EPA predicts average indoor radon levels between 2 and 4 pCi/L here, which puts most homes below the agency's action level. Some will be above it. CDC testing data from Gilmer County puts the average measured radon level at 5.2 pCi/L.
Zone 2 is the one people underestimate. It's easy to hear "moderate" and move on. But within Zone 2, some homes test at 1 pCi/L and others test at 7 pCi/L. The county average doesn't tell you which side your home falls on. Testing does.
A $15 test kit settles the question. If you're below 4 pCi/L, you can genuinely stop thinking about it. If you're above, mitigation systems in Georgia typically cost $800–$2,000 and bring levels down reliably.

Frequently Asked Questions: Gilmer County
If Gilmer County is Zone 2, do I still need to test?
Yes, and this is the one people miss. Zone 2 means the county-level prediction is between 2 and 4 pCi/L, but individual homes span a much wider range. Some Zone 2 homes test at 1 pCi/L, others at 7 pCi/L. You won't know until you test. A $15 kit answers the question for good.
What is the EPA's action level, and why 4 pCi/L?
The EPA recommends fixing your home if it tests at or above 4 pCi/L (picocuries per liter). There's no completely safe level. Radon exposure is a spectrum. But 4 pCi/L is where the EPA concludes mitigation is clearly cost-effective. The WHO sets a lower reference level of 2.7 pCi/L. If your home is between 2 and 4 pCi/L, mitigation is optional but worth considering, especially in bedrooms.
How often should I retest for radon?
If your home tested below 4 pCi/L and nothing major has changed structurally, retesting every two years is a good habit. Retest immediately after any significant basement renovation, after buying or selling a home, or after installing a mitigation system (to confirm it's working). Radon levels can shift as foundations settle and conditions change.
The county average is above 4 pCi/L. Should I be worried about my kids?
Children's lungs are still developing, and they typically spend more time at home, so radon exposure matters for them. The county average above 4 pCi/L doesn't mean your home is above that level, though. Test your specific home. If it comes back high, a mitigation system typically brings levels below 2 pCi/L. That's the right response.
